Good morning, everyone. We are pleased with our results this quarter, which were about our guidance range despite the macroeconomic uncertainty that continued to negatively impact demand in general industrial applications such as cutting and marking. We reported another quarter of solid revenue growth in welding that was driven by record sales and reapplications and all-time high revenue for our handheld welder, LightWELD. Additionally, we saw the strong results in cleaning and solar cell manufacturing. Demand for these products is driven by global macro trends and increasing investment in renewable energy and eco-friendly solutions. IPG is developing innovative technology that enable manufacturing of these products and improve speed and efficiency with benefits to society and environment.
Recently, we published our 2023 annual sustainability report on our website, providing information on many of these trends and how IPG delivers on our new mission statement, "Applying light in ways that improve life." IPG has been making good progress in diversifying our revenue and reducing our exposure to cyclical and economically sensitive industrial markets. While these markets and applications are still account for a major portion of IPG revenue, we have been investing on our R&D, sales, and operating resources to support growth of emerging products and to drive further diversification of our revenues. In the first quarter, emerging growth product sales grew both sequentially and year-over-year and accounting for 45% of total sales. Many of these products are benefiting from global investment in e-mobility and renewable energy.
We saw another quarter of record sales in AMB lasers, driven by growth in EV battery welding as global EV battery capacity build-out continued. We also saw increased demand for our green lasers that are used in solar cell manufacturing applications, improving efficiency of these solar cells. We expect investment in solar cell capacity globally to drive increasing demand for our green lasers in the future. Additionally, our revenue for lasers used in cleaning applications grew significantly in the first quarter. Laser cleaning solution provides sustainability benefits by reducing the use of abrasives and harmful chemicals. For example, a customer is evaluating replacing acid etching with our cleaning lasers. In addition to environment benefits, laser cleaning can significantly reduce cost of storage, transportation, and handling toxic chemicals and eliminate reliance on consumables, which leads to reduced operating expenses.
Our recently introduced laser drying and heating solutions are replacing the less efficient infrared bulbs. The solution are well received by customers and are gaining market acceptance because they cut down on energy consumption and environment impact. We expect orders for this system in the second quarter and anticipate a strong demand for drying system in the future. IPG had another quarter for the second sales of it record sales for e-mobility applications. We are seeing customers accelerating investment in EV battery capacity in North America, Europe, Japan, and Korea. In addition to the investment being made in China. Our e-mobility business in the United States has increased substantially in the first quarter as the customers shifted investment into the region to take advantage of government incentive.
We offer a broad range of solutions to customers from laser source to complete production line for existing and emerging battery technologies. Our real-time weld monitoring solutions and Adjustable Mode Beam Lasers create an industry-leading combinations and addresses customers' challenges, and provides superior weld quality for hundreds of welds in each battery pack. We continue to explore additional opportunity for welding components and electrical motor assembly. With a strong pipeline of opportunities, we are expecting our global sales force focused on e-mobility applications. We expect the EV investment cycle to continue and e-mobility sales to remain strong in the next three to five years. Demands can fluctuate depending on the pipeline of projects and regional capacity additions.
Our medical business had a good quarter and grew year-over-year, driven by continued adoption of our laser system and consumable fibers to, for urology applications. We expect medical sales will be softer in the second quarter as a large customer adjusts its buffer inventory. We are working on multiple new opportunities to broaden our medical portfolio and to further grow the business so it becomes a more meaningful contributor to IPG sales in the next two, three years. I would like to thank our employers for their dedicated work. We believe that an engaged and diverse workforce is a great strength of our organization. IPG has always focused on inclusion and employs a large number of women and workers from diverse backgrounds.
To further improve our diversity, for the first time, we announced targets in our recent CSR report to increase gender diversity and minority representation in the global workforce and management roles. We strongly believe that inclusive work place creates a better future for our company and the community we operate in. I will now turn the call over to Tim Mammen to discuss financial highlights in the quarter.
Thank you, Eugene. Good morning, everyone. My comments generally will follow the earnings call presentation, which is available on our investor relations website. I will start with the financial review on slide four. Revenue in the first quarter was $347 million, a decline of 6% year-over-year due to foreign currency headwinds, which accounted for approximately 4% of the decline in the telecom divestiture that reduced revenue by approximately 1%. Revenue from materials processing applications decreased 8% year-over-year, while revenue from other applications increased 10%. GAAP gross margin was 42.3%, a decrease of 410 basis points year-over-year due to increased manufacturing costs, higher inventory reserves, as well as higher shipping costs and tariffs, which was partially offset by an improvement in absorption as a % of sales.
On a sequential basis, gross margin did show some improvement. FX also had a negative impact in the quarter. If exchange rates relative to the U.S. dollar had been the same as one year ago, we would have expected revenue to be $15 million higher and gross profit to be $8 million higher. GAAP operating income was $75 million, and operating margin was 21.7%. Net income was $60 million or $1.26 per diluted share. The effective tax rate in the quarter was 28% and was impacted by certain discrete items. Foreign currency transaction gains related to remeasuring foreign currency assets and liabilities to period-end exchange rates had a positive impact on operating income of $3 million and positively benefited earnings per share by $0.06.
Excluding the currency transaction gain and a small restructuring charge, operating expenses declined year-over-year, primarily in research and development as we reduced spending on telecom product development, as well as reduced expenses from the sale of the corporate aircraft last year. Moving to slide five. Sales of high-power CW lasers decreased 8% and represented approximately 44% of total revenue. Sales of ultra-high-power lasers above 6 kilowatts represented 42% of total high-power CW laser sales. The decline was primarily due to lower demand in high-power cutting applications due to softer demand and competition in China, which was only partially offset by growth in welding. Pulsed laser sales decreased 16% year-over-year, as strong growth in cleaning and solar cell applications was offset by lower demand in cutting and marking applications.
System sales increased 20% year-over-year, driven by growth in laser-based systems and . Medium LightWELD power laser sales decreased 42%, while QCW laser sales were down 12% year-over-year, negatively by lower sales to consumer electronics applications. Other product sales increased, driven by strong medical sales and increased revenue in advanced applications. Looking at our performance by region on slide six, revenue in North America decreased by 1% due to the telecom divestiture. Growth in welding, cleaning, advanced applications, and medical applications was strong in the quarter and offset lower cutting revenue. In Europe, sales decreased 7% as a result of difficult comparisons, as some growth in the first quarter of the prior year was attributed to pull forward of demand from the second quarter due to supply chain concerns. European revenue increased sequentially despite overall uncertainty in the economy.
Revenue in China decreased 22% year-over-year, as growth in welding for EV battery applications and cleaning applications was offset by continued softness in the cutting market and lower demand in marking applications. Moving to a summary of our balance sheet on slide seven. We ended the quarter with cash equivalents, and short-term investments of $1.1 billions and total debt of $16 million. Cash provided by operations was $37 million during the quarter, and capital expenditures were $33 million in the quarter. First quarter cash provided by operations is typically low due to bonus and tax payments. Our inventory stabilized in the quarter and we continue to target a reduction in inventories during the year.
While maintaining a strong balance sheet, we've been returning a significant amount of capital to shareholders over the last year and continue to do so in the first quarter. During the first quarter, we repurchased shares for a total of $113 million, completing our existing authorization. Today, we announced a new $200 million share repurchase program, another commitment in our efforts to enhance shareholder value by returning capital. IPG has returned a significant amount of capital since the beginning of 2022, repurchasing over $600 million in shares outstanding. Moving to outlook on slide nine. First quarter book-to-bill was one. We continue to see uncertain macroeconomic conditions and soft demand in general industrial markets. Despite relaxing COVID restrictions in China, demand remains relatively muted.
We are still seeing solid activity and orders in e-mobility and renewable energy across all geographies. Despite all of the uncertainty, IPG continues to benefit from growth opportunities created by major macro trends such as electric vehicle battery manufacturing and renewable energy. LightWELD has been gaining traction in the U.S., Europe, and Asia. We believe these trends and continuing efforts to diversify our revenues will make IPG more resilient and drive our growth. For the second quarter of 2023, IPG expects revenue of $325 million-$355 million. The company expects the second quarter gross margin to be between 41.5% - 43.5%.
IPG anticipates delivering earnings per diluted share in the range of $1.05-$1.35, with approximately $47.5 million diluted common shares outstanding. As discussed in the Safe Harbor passage of today's earnings press release, our guidance is based upon current market conditions and expectations, assumes exchange rates referenced in our earnings press release, and is subject to risks outlined in the Safe Harbor and the company's reports with the SEC. With that, we'll be happy to take your questions.
Thank you. At this time, we'll be conducting a question and answer session . Our first question comes from Ruben Roy with Stifel. Please proceed with your question.
Hi. Thank you. Tim, I was wondering if you could expand a little bit on the commentary around demand in China remaining relatively muted. Recently, you characterized some of those applications in China that have been weak, like cutting as, you know, sort of, near or at trough level. Just wondering at this point, if you think there might be a further leg down based on what you're seeing from the order environment or, you know, with reopening. I know there's been some mixed PMI data recently, but, you know, as you think about the second half, do you think that we might see a little bit of improvement off of what potentially could be a trough level? Thank you.
I mean, I think at the moment, demand remains relatively muted, as we'd said. The, you know, expected traction from a recovery is taking longer to really crystallize. I still think we're running relatively speaking on some of the, you know, older industrial applications like cutting, marking, and engraving at that sort of trough level. Continuing to perform very well on EV and some of our precision applications, which now are, you know, a dominant part of our overall revenue there. I think our commentary is in line with what other people are seeing, right? You're not just seeing a very strong rebound post-COVID restrictions being lifted. The PMI data is not particularly strong. You know, for example, in Q1, our relative to our guidance, you know, China did outperform a little bit, so that was a positive.
There was some evidence of a little bit of strengthening, and their Q2 guidance is reasonable. It doesn't show any material pickup compared to Q1. It's relatively flat, but it does point to stability. I think it's way too early to say where the second 1/2 of the year really ends up at this point in time.
Understood. That's helpful. Thanks, Tim. As a quick follow-up, I wanted to touch on some of the emerging markets, which obviously are doing very well, and specifically around EV and how to think about, you know, that marketplace. You doubled revenues, 2021 - 2022. Order rates continue to, you know, remain very strong. Eugene talked about a little bit of a slowdown in medical, as one of your large customers adjusts against buffer inventory. I'm wondering how to think about EV and the order book, you know, going forward. Do you think, you know, some of the new applications that you're addressing are gonna continue to drive momentum or, you know, new customer diversity, et cetera?
You know, is there a period that we might see coming up where you have some equipment utilization and pause in spend in that market? Just kind of wondering how we should think about that, you know, for the rest of this year.
Overall, the EV demand environment remains really quite strong, right? I think the benefit is that where you might see, you know, weakness in one area, it's gonna be picked up in other areas. You know, we're seeing a lot of demand coming out of North America at the moment. Some of that's being driven by some of the benefits that came out of the Inflation Reduction Act. You're starting to see increased investments in Europe as well. You know, China remains quite resilient in that area, but even if there is a bit of a slowdown in one of those geographies, we expect it to continue to be strong in some of the other areas. There's demand we're expecting and we're seeing in some other areas in Southeast Asia as well, like South Korea and even in Japan.
The other benefit is that I think we're gonna start to see orders for the drying equipment materialize during the second quarter, and that should, you know, continue to diversify that revenue stream. I think we have to look at it more on a global basis rather than just specific geographies. We believe that the puts and takes around that will make this still a very sustainable revenue driver for the company.
Also, I would like to add, the very strong growth for revenue is for pulsed laser applications. First of all, for cleaning. For us, it's much more important that we are not selling only just lasers, but also final system of cleaning, including our lasers, scanners, in some cases, a laser monitor and other options. Selling for such kind of product, it also demonstrates a good opportunity for us to penetrate to many different markets per year, related to the cleaning applications.
Thank you, Eugene. Thank you, Tim, for all the detail.
No problem.
Thank you.
Our next question is from Jim Ricchiuti with Needham and Company. Please proceed with your question.
Hi. Good morning. This is actually Chris Grenga on for Jim. Europe and Germany in particular saw sequential revenue growth. Could you provide some additional color on what you're seeing in that region?
I think actually Europe was performed very well in the first quarter, given the challenges that area has faced. You know, I think you started to see really the energy issues that were a key headwind in the middle and 3/4 and even into the end of last year has started to abate. The overall demand environment was quite strong. Some of that was EV, but there was also good demand from some of the cutting applications, particularly in Southern Europe, which helped some of that outperformance. I think the economic data is really stabilized.
PMIs are still not very strong there, but at least the underlying demand was certainly stronger than we'd expected, and the overall tone in the business for the first quarter was quite positive, and that carries on even in the second quarter with the guidance that we receive from the individual entities.
Especially for EV applications, we see such kind of trend that our main potential customer for battery production, they're shifting this production close to their real manufacturing, car manufacturing. Of course, for us it's much more advanced because we are using all our portfolio for different kind of laser options for such kind of production.
Got it. Great. Thank you. With respect to the battery applications, is there any carryover or overlap with stationary battery storage that would be in use in like a residential or like a utility scale solar application, or is it mostly relevant for EV batteries?
Of course, EV battery now is the first place, but battery for storage also is very important, especially for Europe, because it's solar applications may be not so active now, but definitely it will be the growing in the future. This is why the storage battery is very important part of this production. Of course, on the first time now it's on the first place, of course, definitely it's battery for electrical cars.
The application set would be very similar, whether it's on the welding, cleaning, all of that.
Yes.
It's basically pretty standard across those.
Yep.
Got it. Thank you. Just perhaps one more. With respect to, the migration of the production of components that were formerly in Russia, just could you provide a status update on where that stands and perhaps any of the large remaining items on that effort?
First of all, it's not migration of production. We're expanding our production in Germany because it's our standard product for many, many years. By the way, we introduced from Germany to Russia, this production for some simple blocks. All technology is located in Germany. Yes, first of all, we increased our production in Germany, but also installed a new manufacturing place for in Poland and also in Italy. From this manufacturing, now we will have possibility to eliminate any reliance to the Russian production for many different kind of components, including the fiber block, fibers, and other specially fiber-based components.
Very much.
As a reminder, if you'd like to ask a question, please press star one on your telephone keypad. One moment while we poll for questions. Our next question comes from Mark Miller with The Benchmark Company. Please proceed with your question.
Thank you for the question. Could you discuss the automotive market excluding EV?
What do you mean excluding EV? Now, EV is a substantial part of this production. all investment by the way, for example, European car production company mainly are going to EV production, not to standard car production.
and emerging app-
The-
Excuse me.
Yeah, go ahead. Excuse me.
Emerging applications, was that roughly 45% of sales last quarter?
Yes.
Yes.
Okay. Thank you.
We have reached the end of the question and answer session. I'd now like to turn the call back over to Eugene Fedotoff for closing comments.
